The End 10" of tha waive-stem 1O has small bead or 001m": 16, which rests in the! eimular opening in the siidabE-s bearingqfiam 17, seats 'n the recess 18, bufihiag 1%, in which the stem and M) Yests, has an eccentric fiazlga 20, engaging the projecting part 2'1 0f the bearing-plate Y1, and has the lava]? 22, ri idly fixed to said flushing 3.9. A are-- tenir white 23, atmchad 130 Lbs pmjecting '4, sarves 9 Sam, far the bushing 19 retain. the sfidabie bearing-plate 1?, bushing 19 is bald in its seat bythe of the imwwmi g-zzaess maxi while free fmrms naw-Q3115 b The 0penn the and. piaw i5; .ficimxfiy large at free latcrsi movement of Lhe valve stem 2mm; tilted by the: 6L'C6I1L1i6 bushing 19.

The apposite end at the valve-stem has a (a-sad or collar 26, which serves as its bearing-surface in. the bushing 27, seated in, the fismged ofisat 28 of the and late 4 and retained "zhaal'ein by the flangec collar 2? This bushing 2?" permits free lateral. move-- ment of the valve-stem except at the point 033 bearing 0f the annular head 28.

The bushing-2'7 is 11121618 rigid with the disk-- 1 .19.1119: 32 by means of the thread 32 and jam-- n05 1k flexible disk or diaphragm 34, which 1 prefer mm with concantric 001" rugatians, unites the diskiwldar 31 with the valve-stem by means of the thlfiiififid ring nuts 35 and 36. Bolts or pinsfn'i' are an:- plo 'ed to prevent possible displacement of said ring-nuts S5 and 36, and. suitable Offsets 38 are pm 'idad fer the of a, Wrench in connectimn with said. ring-nu Ls.

Tha and 18 of Mm 'vadi'vwstezn is shorter than tim en 19, and when tilted by the eccentric the valved-wk from Hts sea-t, M16

to diser age fixed fulcrum of the stem at the head 26 and the-flexible disk being located in close proximity to the fixed fulcrum, the tilting movement of the valve-stem at this point and the consequent flexing of the disk 34 is very minute.

After the valve-disk is removed clear from its seat movement applied to thehandavheel turns the valve-stem and the valve-disk to any desired degree. The bushing 27 serves as the main bearing and turns with the handwheel and valve-stem, and the flexible corrugated disk or diaphragm prevents leakage, While permitting h ee tilting of the stem. The bead 26 serves only as a fulcrum-point and has no turning function' In closing the valve the valve-disk is brought opposite its seat by the hand-wheel, and the eccentric lever then drives the valvedi'sk tightly against the valve-seat. I

The purposes of having a pair of valvedisks are to counterbalance each other, to lengthen the serviceable life of the valve by substituting the disks alternately, and when throttling to counteract the tendency to shifting of the valve-disk by theblast.

A feature of my invention. is the, system of water-cooling of the valve "parts. A constant supply of cold Water is admitted into the inner passage 12 of the valve-stem, passes straight along said stem, impinges against the bearing portion at the eccentric end,

thence it passes through the outer passage 13 to the disks and along the outer passage of the stem to the discharge connection 40.

Having thus described my. invention, I claim as new anddesire to protect by Letters Patent of the United States' 1. A valve consisting of a casing having a valve-seat attached thereto, avalve-disk attached to a pivotal stem, and means for shifting the axis of said valve-disk.

2. A valve" consisting of .a casing having a valve-seat attached thereto, a valve-disk rigidly connected with a valve-stem, means for shifting the axis of the valve-stem, and means for rotating the valvestem and its connected valve-disk.

3. A. valve consist ng of a casing having a removable valve seat therein, valve-disks at? tached by arms to an axial stem, means for rotating said stem, and means for shifting the axis of the valve-disks.

4; A valve consisting of a casing having a removable valve seat therein, valve disks rigidly attached to an axial stem, means for rotating said disks on their axis, and ecceni tric means for shifting the axis of the valvedisks. I

5. In a valve, the combination with a casing having a detachable valve-seat therein, of a pair of valve-d sks iixed radially upon an axial stem, means for moving said dlsks on their common axis, and auxiliary means for shifting the path of movement of said disks.

6. In a valve, the combination with a cas-- ing having a detachable valve-seat therein,

of opposed valve-disks joined by arms to an axial stem mounted in said casing, means-for rotating said united valve-disks on their axis, eccentric means for shifting saidaxis-stem, and flexible means for preventing leakage when said axial stem is tilted.

7. In a hot-blast valve, the combination with a casing having a hollow valve-seat therein, of opposed hollow valve-disks joined by tubular arms to an'axial hollow stem a continuous stream of cooling fluid so ar-' ranged that the fluid will first impinge upon the bearing parts of said -stem, substantially as and for the purposes set forth.

In testimony whereof I have affixedmy signature in presence of two witnesses.
